Given numbers are 391,639,818,266,391

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 391,639,818,266,391 is 27182072106.

Find LCM of 391,639,818,266,391 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 17 x 23 x 1 x 639 x 409 x 133 x 1 = 27182072106

Therefore, the lowest common multiple of 391,639,818,266,391 is 27182072106.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

391 x 639 x 818 x 266 x 391 = 21256380386892

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

391 : 1, 17, 23, 391

639 : 1, 3, 9, 71, 213, 639

818 : 1, 2, 409, 818

266 : 1, 2, 7, 14, 19, 38, 133, 266

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,639,818,266,391, is 1.

Now, the common factors can be found like this.

391:17x 23

639:3x 3x 71

818:2x 409

266:2x 7x 19

391:17x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 17x 23 = 782

Therefore, the value for common factors is 782.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 21256380386892/(1x782)

LCM = 21256380386892/782

LCM = 27182072106

Thus, we can understand that the LCM of 391,639,818,266,391 is 27182072106.
